The c.676A>G (p.S226G) alteration is located in exon 6 (coding exon 6) of the NIPSNAP3B gene. This alteration results from a A to G substitution at nucleotide position 676, causing the serine (S) at amino acid position 226 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
